摘要:
上下文树是构造无算压缩算法的一种重要基础,作为信息处理过程分析随机序列统计特性的常用数据结构,随机序列中的符号来自于某个固定的符号集合. 上下文树一般是一棵n元树,其中n大于1,但是树是一种占用计算机内存较多的数据结构,因此提出了基于压缩编码的上下文树构造算法,根据符号的一阶统计特性对符号做二进制的压缩编码,用二元树代替n(n>2)元树,在相同内存的存储空间下,可以大大增加树的高度. 计算机数值实验表明基于压缩编码的上下树构造对子串做出了更大长度的相关性检测,并且提高了数据分析的精度.
Abstract:
The context tree as a commonly used data structure plays a very important role in analyzing statistical characteristics of random sequence, and the random sequence of symbols generally comes from a fixed symbol set. The general context tree is a n-tree, in which n is more than 1. Because the tree is a kind of computer memory wasting data structure, a context tree construction algorithm based on compress coding was presented utilizing the first-order statistical properties of binary symbols. In the numerical experiment under the same memory storage space condition, the tree’s height has been greatly increased, and the accuracy of data analysis also improved.
